Construction
36-Inch Water Transmission Main from SH3 to SSH Booster Pump Station
Installation of 17,730 linear feet of 36-inch water supply transmission line will provide an alternative connection from the SH 3 Booster Pump Station to the South Shore Harbor Water Storage and Booster Pump Station. This line will improve water supply to the East side of the City’s water system by providing a third crossing of Clear Creek and provide water system supply redundancy.
The contractor has one air release valve left to install in the Edgewater Community in Webster, which is expected to be delivered and installed by the end of October 2023. The contractor completed installation of the 36-inch waterline under SH 3 and the waterline in an area near the Old Galveston Road. They have also completed an underground crossing of the waterline at the Genco Canal and the jack and bore work at Davis Road and FM 270. The next major phase of the project, which is approximately 50% of the work, is the installation of the fusible PVC pipe. TCH, the City’s drilling contractor, mobilized to the first drill site on May 22nd. Drilling operations of 2,400 linear feet of fusible PVC are complete for this first drill from Shore Harbor Booster pump station and extend to Marina Bay Drive. Preparations for the second drill operation at the Nature Center to the Edgewater Community began in June and completed on August 21st. The 3rd and final drill from the Nature Center on FM 270 to Davis Road began on September 18th and is now complete. The park will remain closed through December 2023. During this time Reytec will restore the park and remove the traffic control devices. Also, lane closures on FM 270 began August 28th and are planned to remain in place until the middle of December. The contractor will also complete the tie in connections between the ductile iron sections and the fusible PVC.
SSH 2MG & Alabama Elevated Storage Tank and Meadow Bend Ground Storage Tank
As part of the Annual Water System Improvements in the CIP program, storage tanks are prioritized for rehabilitation due to corrosion, mineral deposits, and equipment upgrades. This year, the South Shore Harbour Elevated Storage Tank (EST), the Alabama Elevated Storage Tank (EST), and the Meadow Bend Ground Storage Tank (GST) will receive an exterior coating, interior coating, structural inspections, UV exterior coating, and potential structural repairs.
All tank renovations and punch list items are complete at South Shore Harbor EST and Meadow Bend GST, and Alabama EST. Project is in Close Out.
Main Street Waterline Replacement Project I 45 to Palomino Dr
This project replaced nearly 1.5 miles of existing 10-inch waterline along the north side of FM 518 from I-45 to Palomino Lane with a 12-inch PVC waterline. The increase in diameter will provide additional capacity for future needs.
Waterline installation is complete. Testing and chlorination completed in July with substantial completion granted on July 14th. The project has been completed and the intent is to close out all remaining paperwork documentation during the month of December.
State Highway 3 Lift Station Upgrade & Force Main Replacement Project
This capital improvement project will rehab the SH 3 at SH 96 lift station and replace a brick discharge manhole and approximately 310 linear feet of existing 10-inch asbestos concrete (AC) force main along SH 3 between the manhole and the lift station. The project includes coating the interior of the wet well, replacing all existing piping, suction, and discharge equipment, and installing new submersible pumps and controls. Existing piping is currently located inside the dry well section of the lift station, but all new piping will be located above ground, thus eliminating the current confined workspace. New stainless-steel electrical panels, including a generator plug-in connection, will be included in the lift station upgrades.
Two-15 horsepower pumps were recently installed at the bottom of the wet well shortly after interior coating was complete. A temporary tarp enclosure has been placed around the lift station to allow for application of coatings to all exterior mechanical piping and to prevent coating mist from reaching the driving public. Stainless steel electrical panels have been installed along with electrical wiring rough in. The contractor completed installing the permanent perimeter fence and gate, as well successfully completed testing of both sanitary sewer manhole and force main. Electrical service meter has been installed and coordination between the contractor and Texas New Mexico is currently ongoing to establish permanent power. Construction duration is scheduled to complete by December 2023, barring weather or unforeseen delays. 
Glenn Cove LS Dry Pit/Wet Well
The Glen Cove Lift Station Conversion Project consists of structural modifications of the existing dry/wet pit configuration to create a standard submersible lift station. Project scope includes installation of new submersible pumps and associated piping, electrical units and controls, hatches and safety grates, discharge piping and valves, and recoating the wet well.
City Council awarded the construction contract to Matula & Matula Construction, Inc. in June 2022. Contract time for the construction is 320 days and has been extended 242 days for delay in materials. The contractor has installed the new pumps and piping for the expanded wet well. The SewperCoat installation (rebuilding approximately 6” of interior wall) in the old wet well is complete and the SpectraShield coating (in the expanded wet well) is also complete. The new electrical platform and equipment is installed allowing crews to continue with underground electrical and electrical hook-ups the next few months. Construction is estimated to be complete February 2024. 
DSWWTP SCADA Upgrade Project
Functional System Control and Data Acquisition (SCADA) systems are required to monitor, control, collect data, and ultimately integrate the multitude of process functions throughout the many treatment components of a wastewater treatment facility. This project replaces and updates all software and hardware related to the fiber looped SCADA system that serves the Dallas Salmon Wastewater Treatment Plant (DSWWTP).
Prime-Controls has completed the installation of the UV hardware and programming is ongoing. Belt press and aeration blower work is anticipated to begin in early October with substantial completion by the end of January. The contractor has requested additional time to complete the project, to the end of January, due to staff shortages and material availability with vendors. City staff approved the time extension.
Dallas Salmon Wastewater Treatment Plant RAS Pump Improvements
The RAS pumps are an integral part of the activated sludge system, the purpose of the pumps is to manage solids levels in the aeration basins and secondary clarifiers to ensure optimum treatment efficiency. This system must be reliable and meet the peak flow demand. This project will provide modifications and replacement of the six existing horizontal end-suction RAS pumps, removal and replacement of associated suction and discharge piping, as well as replacement of the RAS pinch valve, including a maintenance bypass loop used to control the RAS flow to the aeration basins.
All six (6) pumps at RAS pump areas have been installed are online and in use. Construction is complete. A substantial site walk was competed on October 19th. The contractor is currently working on the punch list from the substantial walk through. A final walk through will be scheduled 30 days from the substantial.
15” Willow Branch & 18” FM 518 Gravity Line Replacement
Construction of these improvements will increase the size of the approximately 1,400 feet of existing 18-inch sanitary sewer along FM 518 to 21 inches and increase the size of approximately 1,800 feet of existing 12-inch sanitary sewer along Washington Street and Willow Branch Drive to 15 inches. The upsized gravity lines will adequately convey existing and projected peak wastewater flows through the year 2037, as projected by the City’s Wastewater Masterplan, and will help maintain regulatory compliance regarding sanitary sewer overflows.
Construction crews have installed the sanitary by-pass from Calder Rd. to Wesley Dr. along FM518 and have replaced approximately 960 linear feet of 18-inch sewer line with 21-inch sewer line and working on manhole replacements. The contractor brought in a second crew to expedite work in the Oaks of Clear Creek along Washington St. and Willow Branch Dr. Crew A is continuing work along FM518 and Crew B is currently installing silt fencing and staging sewer pipe along Washington St. In the next few weeks, Crew A will be finishing up work along FM518 and Crew B will be setting up by-pass pumping and conducting pipe-bursting operations along Washington St. and Willow Branch Dr. Construction is anticipated to continue through March 2024.

Design
There are several projects in varying stages of design.
The Calder South (Well, Generator & BPS), formerly called Westside Well & Booster Pump Station, will provide additional water supply to the City’s water distribution system and a redundant water source to Bay Colony and south-central areas of the city. During evaluations of the water infrastructure for the updated Water Master Plan, the proposed scope of this project was revised and expand to consist of a new groundwater well and 4,500 gpm booster pump station located on Calder Road along with a connection to the waterline transmission line from the TMWTP. The scope includes construction of a new pump building with miscellaneous piping, pumps, electrical equipment, and controls as well as a new chemical feed system, a 1.0MG ground storage tank, SCADA system, generator, and a Water Meter Base Station for GCWA. The project has also been renamed Calder South (Well, Generator & BPS) with design funded in 2024 and construction in 2026.
The Mary Lane and Tallow Forest Service Area Connection will connect existing 8" waterlines to the City water system as they were previously served by WCID #1. Surveying is complete. The scope has been revised to add force main relocation from FM 517 & Mary Ln to Hobbs and Wikiup St. 60% plans have been submitted and are currently under review. City Council approved an amendment to the design contract on 11/28 to include updating the existing lift station which will improve the electrical system, pumps and add safety features.
The East Main 24" FM Replacement is the FY 22 design selected for an annual program consisting of the engineering evaluation and strategic rehabilitation of sanitary sewer systems as identified as a priority throughout the City. The project will replace approximately 5,300 L.F. of an existing 24-inch diameter sanitary sewer force main constructed in 1981 serving the East Main Lift Station. The existing 24-inch force main is located along FM 2094 (TxDOT ROW), crosses FM 2094 and runs south of Bayou Brae Subdivision, crosses Robinson Bayou (Clear Creek), and runs along Coryell Street until it crosses FM 270 (TxDOT ROW) and discharges into the manhole that is located on southeast corner of FM 270 and Coryell Street. Coordination with TxDOT for approval to install the proposed force main replacement will be required. The 100% design plans were just received. The project has been cleared from needing any permitting from the US Army Corps of Engineers.
The Jarbo Bayou Force Main Replacement scope includes replacement of the existing 6" force main encased in concrete through the bottom of the channel from the discharge of the Harbor Park 3 Lift Station to an air relief valve on the opposite side of the Bayou to avoid possible breakage and contamination of the Bayou. New line will be adjacent to the existing force main and placed in a casing across the Jarbo Bayou. Survey is completed. Project status meeting was held in late April and initial design submittal was reviewed. 60% design plan comments have been returned to the consultant to be addressed in preparation for the 90% submittal. The project is waiting for approval from USACE regarding a permit to perform the work. If no issues are identified with USACE, the project will be bid and started in 1Q 2024.
The East Main LS Dry pit/wet well submersible conversion project consists of structural modifications of the existing dry/wet pit configuration to create a standard submersible lift station to provide more reliable service during tropical weather events. The project scope includes installation of new pumps and piping, new controls and electrical system, structural modifications, new hatches and safety grates, new discharge piping valves, and coating of the existing dry pit/wet pit. The conversion provides additional wet well capacity by combining the two pits, keeps the City workers above ground, and allows pumps to be pulled out for inspections and repairs with much more reliability with the least health and safety risks. 60% design plans were submitted in September with comments returned in October. Design is expected to complete in the first quarter of 2024.
Annual Odor control improvements are a part of the CIP. Smith Lane and Butler Road LS Odor Control were the projects identified for design and construction in FY 22/23. Improvements planned are removal and replacement of the odor control units for the Smith Lane and Butler Lift Stations as well as modifications to the piping, structural and electrical and instrumentation. The fence will also be modified/replaced, and site work designed for the expanded Butler Lift Station site. Design is currently at 90%. Sander Engineering is working on the 90% DRC comments and preparing the 100% plan submittal. A replat of the property is required and City staff anticipate to bid this project in early February.
The city completed a Reuse Feasibility Analysis in 2014. Since completion of that study, the city has taken actionable steps to reduce potable water consumption within the City while increasing “reuse” customers. A contract to update the 2014 study was awarded by Council in May 2022. The report will be done in four phases which include: data collection and analysis; identifying potential users and subsequent planning and cost to serve; development of an implementation plan; and final report and exhibit production. Data collection and analysis is currently ongoing. The consultant has held several workshops to discuss data findings and coordinate with the city. The final workshop was held in August 2023 and the report is being finalized.
The Harbour Park 1 LS Expansion was identified in the 2018 Wastewater Master Plan and further evaluated in a Feasibility Study performed in early 2023. The study was conducted to assess the current condition and define the scope for the project to increase the firm pumping capacity of the lift station from 1.6 MGD to 3.0 MGD. The study also looked at a possible increase in the size of the incoming gravity sewer from 18” to 21”. Upon completion of the Study and budget appropriation, staff opted to do a phased implementation of improvements. The initial phase will expand the station to 3 MGD, provide emergency power and remove and replace 45 feet of 18” gravity sewer with 21” line in front of the station. The proposed improvements will reduce surcharging during extreme weather events and allow the City to maintain regulatory compliance regarding Sanitary Sewer Overflows (SSO’s). The final design contract was approved via Council action August 22nd and the Notice to Proceed was issued on August 23rd. The 30% submittal was received in mid- October 2023 and the review was completed at the end of November.
